I just upgraded my laptop from Ubuntu 8.04 to latest Xubuntu via Synaptic Package Manager. I also uninstalled Ubuntu via terminal command.

Everything works fine, except the wireless card. When I login the wireless connection is unavailable and I when I go to System > Hardware Drivers I see that the wireless card's driver is enabled but unavauilable. If I uncheck the driver option and then check the option again, it comes online and I get connection, but by laptop shows that I need to restart. After I restart, everything repeats again -- I have to enable the card mannually again.

How can I fix this?
